Had Janitrol installed 10/3/97. It started freezing up and dropping ice about a year later ruined bathroom ceiling and I am still trying to get them to fix it. Had numerous service calls which all they did was replaced the freon which I had to pay for. They are suppose to replace coil but haven't seen it yet. This has been going on for 2years. Don't know if it is the coil that is causing probem. I would never recomend this unit it's better to pay a little more and get a good one.
